Pascal Parraud commented on MATH-388:
-------------------------------------
After a few tests, the patch:
* seems ok for DormandPrince853Integrator,
* seems ok for GraggBulirschStoerIntegrator, with 2 fixes :
** in GraggBulirschStoerIntegrator, y0.length changed into scale.length (or
mainSetDimension) at lines 712 & 716 ( integrate method),
** in GraggBulirschStoerStepInterpolator, currentState.length changed into
scale.length at lines 302 & 306 (estimateErrror method),
* needs to be tested for others integrators.
And, waiting for a new architecture, ODEWithJacobians & ParameterizedODE
classes should extend ExtendedFirstOrderDifferentialEquations instead of
FirstOrderDifferentialEquations.

> The user should be allowed to chose a tolerance vector dimension different
> from the state vector dimension.
> For example, using the FirstOrderIntegratorWithJacibians, we don't want to
> set some tolerance error for the jacobian part in order to not interfere with
> the main state vector integration.
> This is really a problem with the dimension of the tolerance vector, there is
> no work-around assigning some particular value to the tolerance vector.
